we had a great stay here! the place is centrally located and close to good food! Klass was very responsive and answered all of our questions.
check in was easy and the apartment was sparkling. only small issue was the bathtub in the master holds water along the edge of the tub, and needs a good scrub.
the personal touches, like welcome drinks, first aid kit, and movies were welcome. I definitely recommend this place if you are staying in Bangkok!
